A production sound mixer is responsible for recording all sounds on set including effects, foley, and ambience. Is this statement true or false?

The statement is false. A production sound mixer primarily focuses on recording dialogue and live sound on set during the filming process. While they may capture some environmental sounds, sound effects, and ambience, their primary responsibility does not typically encompass foley, which refers specifically to the reproduction of everyday sound effects that are added in post-production to enhance audio quality. Foley is created separately in a controlled environment after the filming has concluded, making it the job of a foley artist rather than the production sound mixer. Thus, the role of the production sound mixer is not inclusive of all sounds—particularly those that are crafted in post-production, such as foley.
